I've been hiring and managing developers and engineers for almost 20 years, and I don't/won't do any of this nonsense. During the course of a single interview I describe what we are building and how we are building it, and invite the candidate to explain if/how they could participate in that. One or two senior guys from the team will ask them some smart questions about real-world problems and complexities to get a sense that they know their stuff. No quizzes or puzzles or abstract questions. No homework. No second or third or fourth interview.
